【摘要】 汞为煤中痕量元素,在煤燃烧过程中将会排放到大气中,给环境和人类健康带来危害。采用活性炭对汞的排放进行控制。对原始的活性炭颗粒用硫化钠、氯化锌浸泡进行活化处理,研究了他们的汞吸附性能。结果表明:活化处理后能有效提高活性炭的汞吸附性能,而且,用氯化锌处理的活性炭的汞吸附性能要好于硫化钠处理的。更多还原

【Abstract】 The trace element Hg is released when the coal is burned. It does great harm to environment and mankind health. The experiments on mercury adsorption by activated carbon impregnated with ZnCl2 and Na2S are presented. The results indicate that it can increase the adsorption rate of activated carbon after activation, and the adsorption rate of activated carbon impregnated by ZnCl2 is better than by Na2S.更多还原
